CORN PLANTER Filed April 1, 1957 i. [Jem lLgsA aux nu Patented Oct.Y 25, 1938 r .l UNITED. STATES PATENT OFFECE y y 2,134,612 Y CORN PLANTER Lilburn I. Jennings, Nickelsville, Va; Application April 1, v1937, Seriai'NO. 134,404

` solaims. (01221-122) 'Ihis invention relates to a corn planter and it aims to provide a novel construction wherein discharge of a predetermined amount of fertilizery simultaneously with the'seed is assured, so as to avoid the waste or discharge of fertilizer,

It also aims to provide novel means whereby the fertilizer is agitated to avoid undue packing thereof.

The lmore specific objects and advantages will l0 become apparent from a consideration ofthe description following taken in connection with accompanying drawing'illustrating an operative embodiment. l

In said drawingi Figure 1 is a view ofthe planter in perspective;

Figure 2 is an enlarged partial plan view;

Figure 3 is a vertical sectional view taken on the plane of line 3-'3 of Figure 2, and

Figure 4 isa vertical sectional detail taken on Athe line 4-4 vo f Figure 3.

Referring specifically to the drawing wherein like reference characters designate `like or similar parts, the planter consists of a suitable frame I0 to which draft means is hitched in any suitable manner, the frame having a crossbar II mounting an axle I2 upon which a pair of ground wheels I3 are journaled. Y

A suitable hopper I4 is mounted on the frame Il'l, being secured in place as by means of brackets I5 or the equivalent. Said hopper has compartments I6 and I1, respectively adapted to contain corn orother seed and fertilizer. A bottom wall I8 ofthe hopper extends across both compartments I6 and I1 and such bottom wall has discharge openings I9 and 20 therethrough, for the seed and fertilizer, respectively, under control of a valve or plate 2l. Disposed on the top of the bottom plate I8, with the openings I9 and 20 also extending through it, is aY wear plate 22 and disposed thereon in laterally spaced relation are auxiliary wear plates 23. The valve 2| is disposed betweenthe wear plates 23, being preferably of metal like the wear plates 22 and 23, and which plate 2I is reciprocable in longitudinal direction, extending through an opening 24 in the partition 25 which divides thechambers I6 and `I1. Valve 2I also has a seed discharge opening or port 21 therethrough.

A pair of brackets 28 are fastened over the auxiliary wear plates 23 and they have vertical flanges l29 in laterally spaced relation to and between which a flap 30 is pivoted at 3l, norl*mally resting on a stop 32 bridging such flanges.

, Brackets 28 alsov havey extensions 33 which are disposed in theopening 24 to protect the partition 25 against undue wear due to the reciprocation of the valve 2I.v

Depending from the bottom wall I8 is a discharge Stube 35 in communication with both the 5 openings or slots I9 and 2U. At times the opening or slot 20 is closed by a Vgate 36 pivoted at 31 to the wall I8. At times the gate 36 closes the slot 2D due tothe fact that a lug 38 on a reciprocable arm 39, engages the same from below. Said 10 arm 39 is preferably rigidly connected with the valve 2l, specifically to a forward extension 48, at 4I. In the rearmost position of the lug 38, it disengages the gate 36 so that the latter may fall to a vertical position. Y 15 An agitator 42 of any desired construction, is disposed within the chamber or compartment I1,

. so as to prevent undue packing of the fertilizer.

Such agitator has a shaft 43 journaled in the Walls of the hopper I4 and extending to the exterior 20 thereof.

'Ihe power for operating the valve plate 2| and the agitator 42V is derived from the aforesaid axle I2 to which end it has a gear wheel 44 keyed thereto and enmeshed with a gear wheel 45 keyed 25 to a transverse shaft 46 mounted in suitable bearings 41 on the frame I8. An eccentric or disk 48 is fixed on one end of shaft 46 and a pitman 49 is eccentrically connected to it and loosely connected at 50 to the valve 2I. In addition, a 30 pulley 52 is keyed to shaft 46 and a pulley 53 is keyed to shaft 43. Said pulleys 52 and 53 are preferably covered with rubber to increase the friction at their peripheries over which a belt 54 is trained. 35

In the operation of the device, considering the valve ZI in its forward position, the fertilizer from chamber I1 falls through opening 20 ontoV the gate 36 and at the same time a seed from the supply in chamber I6 enters opening 21, resting 40 on the plate 22 therebeneath. On the rearward movement of the valve 2|, it will close the opening 20 and dispose the opening 21 with the seed therein beneath the flap 39. At the time plate 2I closes opening 20 and opening 21 registers with opening or slot I9, the lug 31 disengages the gate 36 so that the latter falls to the vertical position of Figure 3, simultaneously discharging the seed and fertilizer through the slots I9 and 28 into the tube or chute 35 from which they fall into the desired hill, furrow or the like. During such operation, the agitator 42 continues to rotate through the gearing previously traced.

Various changes may be resorted to provided 55 they fall within the spirit and scope of the invention.

I claim as my invention:

1. A distributor of the class described comprising a hopper having seed and fertilizer chambers, a bottom Wall for the hopper having slots therethrough communicating one with each chamber, a valve slidable over said bottom wall to cut-olf the slot from the fertilizer chamber, said valve having an opening to convey seed to the other slot, baille means in the seed chamber disposed over the valve at the position of discharge of the opening thereof, a gate beneath the slot for the fertilizer, and means movable with the valve to control the opening and closing of said gate.

2. A distributor of the class described comprising a hopper having seed and fertilizer chambers, a bottom wall for the hopper having slots therethrough communicating one With each chamber, a valve slidable over said bottom wall to cut-off the slot from the fertilizer chamber, said valve having an opening to convey seed to the other slot, baille means in the seed chamber disposed over the valve at the position of discharge of the opening thereof, a gate beneath the slot for the fertilizer, means movable with the valve to control the opening and closing of said gate, consisting of an arm and a lug extending laterally from the arm engageable and disengageable with the lower surface of the gate.

3. A distributor of the class described comprising a hopper having seed and fertilizer chambers, a bottom Wall for the hopper having slots therethrough communicating one with each chamber, a valve slidable over said bottom wall to cut-olf the slot from the fertilizer chamber, said valve l having an opening to convey seed to the other slot,

baille means in the seed chamber disposed over the valve at the position of discharge of the opening thereof, -a gate beneath the slot for the fertilizer, means movable With the valve to control the opening and closing of said gate, a Wear plate on the bottom plate, auxiliary Wear plates on the bottom plate, and said valve being disposed on the first mentioned Wear plate between the auxiliary Wear plates.
